Martin, 17, was killed while walking to his father's fiancee's house in Sanford from a nearby convenience store.

Zimmerman first called police atĀ 7:09 p.m. ET with concerns about a suspicious teen in the area, according to 911 tapes released by the Seminole County Sheriff's Department.

A 16-year-old girl who was on the phone with Martin most of the day last spoke to him around the time the incident allegedly began and lasted until 7:16 p.m. ET, when the call dropped. Almost immediately, 911 calls began coming in.Ā Ā Police arrived on the scene at 7:17 p.m.

Several witnesses called 911 at 7:16, 7:17, 7:18 and 7:19 p.m. ET.

Below are the transcripts of the calls as Zimmerman and witnesses describe what they saw and heard that night:

7:09 p.m. ET

Dispatcher: "Do you need police, fire or medical?"

Zimmerman: "We had some break-ins in our neighborhood ... and there is a realĀ suspiciousĀ guy. ... This guy looks like he's up to no good, he's on drugs or something. It's raining, and he's walking around looking about. "

Dispatcher: "Is this guy white, black,Ā Hispanic?"

Zimmerman: "He looks black."

Dispatcher: "Did you see what he's wearing?"

Zimmerman: "A dark hoodie, grey hoodie, jeans or sweatpants or white shoes. He's walking around staring at the houses. Now he's just staring at me."

Dispatcher: "Location?"

Zimmerman: "He's near the clubhouse right now. Now he's coming towards me. He has his hands in hisĀ waistband. He is a black male. Something's wrong with him. Yep. He's coming to check me out. He's got something in his hands. I don't know what his deal is. Send officers over here."

Dispatcher: "Let me know if he does anything else."

Zimmerman: "These a**holes, they always get away. When you come in go straight to the left ... when you pass the clubhouse ..."

Zimmerman: "Tell them to come past the clubhouse and make a left then past mailboxes and they will see my truck ..."

Dispatcher: "What's your apartment number?"

Zimmerman: "It's a home. ... IĀ don'tĀ want to give that out. I don't know who this kid is."

Dispatcher: "I will let them know where to meet you."

Zimmerman: "Have them call me, and I will let you know where I'm at."

During part of this time, Martin is on the phone with a 16-year-old girl. Below is an account of the phone call as relayed to In Session's Sunny Hostin by a lawyer for the Martin family:

Martin told the girlĀ someone was following him, and she advised him to run. Martin said he isn't going to run but will walk quickly. Zimmerman caught up with him, and Martin asked Zimmerman why he was following him. Zimmerman then asked Martin his name and why he was there. The girl on the phone says she heard Zimmerman push Martin, and then the call drops. She tried to call Martin back, but he didn't respond.

Caller: "No, I don't because I'm hiding upstairs. The gunshot was outside our house. You sent somebody, right?"

Dispatcher: "Do you hear any vehicles leaving or anything else?

Caller: "There's people yelling down there, but I don't want to go down there."

Dispatcher: "People are yelling now?"

Caller: "Yeah."

Dispatcher: "We do have officers on the way. Call us back if you see any vehicles leaving or anything."

------

7:16 p.m. ET

Dispatcher: "Police, fire or medical?"

Caller: "There's someone screaming outside."

Dispatcher: "Is that at where you are at?"

Caller: "Oh, my God, there is a gunshot, hurry up."

[inaudible]

Dispatcher: "Do you see anybody? I don't need you to go outside."

Caller: "There is someone screaming. I just heard a gunshot."

Dispatcher: "Do you see anything? I don't need you to go outside. Do you hear screaming or anything?"

Caller: "Hurry up, they are right outside my house."

Dispatcher: "OK, we [have] police and emergency, OK. Are you in Sanford?"

Caller: "I see police now."

Dispatcher: "You see the officer?"

Caller: "Yeah, but like it's behind the house. There is a dead body there. It's not the front entrance. Oh, my God."

Dispatcher: "Please tell me so I can tell them."

Caller: "If you are looking at my house, it's behind by my back porch."

Dispatcher: "Coming from behind your house?"

Caller: "Yes, the back porch."

Dispatcher: "Stay on the line and update me."

Caller: "I just heard screaming and a gunshot."

Dispatcher: "We have an officer there. Did you hear any more gunshots?"

Caller: "No, I don't hear. Hurry up, hurry up."

Dispatcher: "OK, we have officers out there, OK? If anything changes, give us a call back, but we do have officers there. One officer is there."

Caller: "OK, did he see anything?"

Dispatcher: "I'm not sure, ma'am, I just know he is there, and two other officers are on their way, OK? If anything changes or anything more, call us back. As far as you know, it's coming from behind your house near yourĀ back-porchĀ area? When you hear screaming, was it screaming of female or male?"

Caller: "Male."

Dispatcher: "So, when you heard screaming, it was a male screaming?"

Caller: "Yes. And the guy on top had a white t-shirt."

Dispatcher: "What do you mean guy on top? Did you see a fight?"

Caller: "IĀ don'tĀ know, I just looked out my window, and there was a guy on top wearing a white t-shirt."

Dispatcher: "A white t-shirt. Did you see what kind of pants? He was on top of what?"

Caller: "I couldn't see the person he was on."

Dispatcher: "But he was on top of a person?"

Caller: "Yes."

Dispatcher: "The guy with the white t-shirt, did he get up and run?"

Caller: "I don't know. Went to the phone to call you

Dispatcher: "White, black orĀ Hispanic?"

Caller: "I couldn't tell, it was completely dark."

Dispatcher: "We have several units en route."

Caller: "Thank you."

7:17 p.m. ET

Dispatcher: "Do you need police, fire or medical?"

Caller: "Iām looking out my deck, and someone is screaming 'help,' and I donāt know. ā¦ I heard a bang. Iām looking out my window, out my backyard, and someone is yelling and screaming 'help.' "

Dispatcher: "You are not the only person calling. We have more than one officer on the scene and another on the way."

Caller: "Oh, my God. I see the person now. I see him walking. Thereās a man coming out and people coming out with flashlights. Oh, my God. I donāt know what he did to this person. I can see there is a man walking out with a flashlight right now."

Dispatcher: "Was it a male or female voice?"

Caller: "The man is up right now. Someone is coming over. Iām glad other people called."

Dispatcher: "We should be out there right now."

Caller: "I can open my window and hear it."

Dispatcher: "You can still hear it?"

Caller: "I donāt know what is happening. Someone is laying on the ground."

Dispatcher: "Whatās happening? Someone is on the ground? Someone has been shot? Calm down, stay on the line with me. Like I said, we have an officer on the scene, and we have other officers on the line."

Caller: "Oh, my God. They better hurry up. Someone is on the ground. Oh, my God! I see out my back window, sidewalk, grass, something is really bad. There is a man out here with a flashlight."

Dispatcher: "Is this person laying down in the street?"

Caller: "No, it's from my back window."

Dispatcher: "So is the person laying down in the street or in the grass?"

Caller: "The grass. Oh, my God! I think there is another gentleman with a flashlight. ... I think police. Oh, my God! He shot, he shot the person.He says he shot the person. He said he shot the person."

Dispatcher: "Who saying they shot who?"

Caller: "The people out there, a guy is raising his hands up, he's saying he shot a person. I think it's a police officer that's with him right now. arrest - uh - oh, my God, why - why (inaudible)"

Dispatcher: "Our officer is there, he has somebody at gunpoint. They're going to handle the situation from here."

Caller: "Oh! Oh, my God, somebody would be shot!"

Dispatcher: "It's probably going to be best if you stay inside your home for the time being, OK?"

Caller:" I know. I can't believe somebody's killed. He was saying help. Why didn't someone come out and help him?"

Dispatcher: "Listen, we don't know if they been killed ..."

Caller: "Yes, the person is dead, laying on the ground."

Dispatcher: "Just because he's laying on the ground don't mean he's passed. We have an ambulance on the way, and we are probably going to pick him up and take him to the hospital."

Caller: "I didn't see cause it was too dark, and I just heard people screaming 'help me, help me.' And this person shot him! He was like wrestling with him, you know what I mean, on the ground, from what I can see it was very dark. The man didn't try to run away or anything. I don't want to be a witness or anything. I'm scared. Oh, my god, a young boy, I can't imagine, I haven't seen anyone killed. This is a nice neighborhood. Oh, my God, I'm too scared to live here."

Dispatcher: "YouĀ don'tĀ have to worry right now. We have many officers on the way. Two officers on scene right now, we are on scene, OK?"

-----

7:17 p.m. ET

Dispatcher: "Do you need police, fire or medical?"

Caller: "Police. I just heard a shot behind my house. They are wrestling outside the back of my porch."

Dispatcher: "You just heard one shot go off?""

Caller: "It was either that or a rock at the window or something else. The guy's yelling 'help,' and I'm not going to help."

Dispatcher: "So you can hear someone yelling for help?"

Caller: "I'm pretty sure the guy is dead out here. Holy s***"

Dispatcher: "OK, we have several people calling in. Anything else that you heard?"

Caller: "A guy yelling, 'help.' Oh, my God! There is a guy with a flashlight in the backyard now. I think there's flashlights and a guy. ... I don't know if that's a cop. "

Dispatcher: "OK, we have several calls. Are you sure when you heard voices it was one person yelling, right?"

Caller: "There were two guys in the yard with flashlights, and there is a black guy down like he's been shot, and he's dead."

Dispatcher: "I have several officers going out there."

----–

7:17 p.m. ET

Dispatcher: "Do you need police, fire or medical?"

Caller: "Medical. IĀ think someone has been shot."

Dispatcher: "Why do you think someone has been shot?"

Caller: "Because they are laying in the backyard and a gunshot and they said 'call 911.' Now there are people coming with flashlights ..."

Dispatcher: "And it's in the backyard?"

Caller: "Yes."

Dispatcher: "And someone is laying in the backyard?"

Caller: "Yes, there are people around him now."

Dispatcher: "You there with kids?"

Caller: "Yes, my daughter. He is a black guy."

Dispatcher: "We have units on the way. What do you mean it's a black guy?"

Caller: "There is a black male standing over him."

Dispatcher: "Can you tell me what he's wearing?"

Caller: "I think someone else called 911."

Dispatcher: "You do see officers out there?"

Caller: "Yeah, IĀ think that's the flashlights that we see."

-----–

7:18 p.m. ET

Dispatcher: "Do you need police, fire or medical?"

Caller: "This is 911, correct? Police or medical. Someone is yelling two doors down from me, screaming, hollering 'help, help, help.' There is an elderly man that lives down there. I don't know. I heard a gunshot. I don't know if it would be ambulance."

Dispatcher: "How many shots did you hear?"

Caller: "One."

Dispatcher: "How long ago?"

Caller: "As soon as I heard that I picked up the phone and called."

Dispatcher: "Before calling 911?"

Caller: "Yes. There is somebody out by myĀ back porch. ... There is someone walking around with a flashlight. The police may already be here. I don't know. Someone is out there with a flashlight, but I did hear something."

Dispatcher: "We do have units there."

Caller: "Oh, my God."

Dispatcher: "And the screaming, was it a male or female you heard?"

Caller: "It sounded to me like a male, and from what I know and I've been here four years, there is an elderly man that lives like four doors down, um, north of me, and I'm inside."

Dispatcher: "Do you think it's coming from your area?"

Caller: "I don't know, ma'am, I'm standing at my back sliding glass door. I don't see anything but a flashlight shining around, but I did hear someone yelling 'help, help, help' or 'oh, my gosh' and something, then moaning and a boom, and I picked up the phone and called."

Dispatcher: "Did you see or hear anything else like a vehicle pulling away?"

Caller: "No, ma'am, because I'm in the back, and in the back there is just a walkway. It could have been someone in the front with a car, I don't know, but I was in the back. It was scary. There is someone still back there with flashlights walking around."

Dispatcher: "There should be someone on the scene ..."

-----–

7:19 p.m. ET

Dispatcher: "Do you need police, fire or medical?"

Caller: "My brother said someone got shot behind our house."

Dispatcher: "Is your brother out there right now?"

Caller: "No, he ran in the house."

Dispatcher: "Do you know who was shot?"

Caller: "No idea. ... I'm inside. It's behind our house. ... Yeah."

Dispatcher: "You didn't see or hear anything else? Did you hear the shot?"

Caller: "I heard something, and my brother ran in the house."

Dispatcher: "My brother saw it."

Dispatcher: "What did you see?"

Caller: "I saw a man laying on the ground screaming who needed help. I was going to go over there to try and help him, but my dog got off the leash, and I ran and got him, and I hurried around and down, and the screaming stopped."

Dispatcher: "Did you see the person get shot?"

Caller: "No."

Dispatcher: Did you know the person who got shot, or did you see the person with the gun?"

Caller: "No, I just heard a shot, and the screaming stopped."

Officers arrived on the scene at 7:17 p.m. ET, according to a police report.

Officers Timothy Smith and Ricardo Alayo said they noted a black male in a gray hooded sweatshirt lying face-down in the grass, as well as a white male in the area.

"Zimmerman stated that he had shot the subject and was still armed," Smith wrote in a police report.

Smith said he asked Zimmerman to hand over the weapon, a Kel Tec 9 mm, and handcuffed him.

"While I was in such close contact with Zimmerman, I could observe that his back appeared to be wet and he was covered in grass, as if he was laying on his back on the ground," Smith wrote in the police report. "Zimmerman was also bleeding from the nose and the back of the head."

The officers also made several attempts to revive Martin.

When police put Zimmerman in the back of the cruiser, he said, "I was yelling for someone to help me, but no one would help me," according to the police report.

They have to prove that the girlfriend was on the phone with Martin. There's something wrong with the timing. Supposedly the girlfriends call drops at 7:16 after hearing Martin being pushed, yet at 7:16 the first call to 911 from a resident came in and she described that someone was outside yelling "help" for some time. She heard someone outside, made a decision to call 911 and place the call prior to 7:16. The shot did not go off until 45 seconds into that 911 call. At some point, the boy with the dog saw someone laying on the ground, and someone else saw a guy in a white shirt on top of someone. All of that took place before 7:16. I'm saying it's impossible for both the girlfriends phone call and the first 911 call to take place in the same minute. At 7:09 the Zimmerman 911 call was placed and that call took 4 minutes 11 seconds. So at least at 7:13:11 he left his vehicle. Which leaves 2 minutes 49 seconds before 7:16. There must have been an assault prior to 7:16 that took place. What the girlfriend describes could not have happened, her call would have had to drop long before 7:16.

I see a lot of folks say that 911 dispatchers are not police officers and thus Zimmerman does not need to listen to them. But you have to remember that even they have more authority than Zimmerman. Zimmerman is a volunteer, 911 dispatchers are hired and trained employees. From a recent case about a white woman who shot an intruder after the 911 dispatcher gave her the go ahead and her state approved, it is my understanding that most 911 dispatchers do hold authority. That aside, after Casey Anthony and a couple of past cases, I've decided to have a neutral mind when this case goes to trial. Justice in the hands of man can be very disappointing, I choose to believe in God and I choose to leave justice in his hands. Even an idiot like Zimmerman deserves to be forgiven before he dies of some cause. RIP Trayvon

pleasedotell it really sounds like you are defending Zimmerman! Also, Zimmerman was NOT a "volunteer" he was a backwards racist @$$hat who saw a black kid and then MURDERED him for the simple fact that he was a black kid walking around! He claims he shot Trayvon in "self-defense" how the h*ll do you need to shoot somebody, a CHILD, who's unarmed, and running AWAY from you?!! Trayvon wouldn't have been running in the first place if creepy murderer Zimmerman wasn't FOLLOWING him! I'd do the same thing if somebody was following me! Casey Anthony got off basically on technicalities, but there's TOO MUCH evidence against Zimmerman for him NOT to be arrested, charged, and prosecuted. He was so worried about an innocent boy with a bag of skittles, but I feel safer with boys like Trayvon walking around free than with people like Zimmerman. He is a MONSTER, the absolute worst kind of monster and at this point I don't personally feel that he deserves any forgiveness because he obviously is not sorry for his actions. HE pursued Trayvon, then killed him. This makes me SO ANGRY and I'm even MORE angry that nothing more has been done yet!

This zimmerman fellow thought he was a hero boy tried to takle the kid as you can see had a bright future in football and other sports..zimmermans out of shape azz got beat up during the process and yelled help prob then shot the kid in the back as he ran..brilliant real brilliant zimmerman ..and who all in the village took a vote for him to be team leader in the watch program ?..hang yourselves..stanford police squad is obviously a joke..add insult to inury and drug tested the dead kid while the biggot goes free? everyone wrongly involved should person deliver themselv es to hell in a handbasket...thank you for your attention!!

HoustonSteve, YES, even if Zimmerman genuinely thought the kid was a criminal, when Zimmerman attempted in any way, shape, or form to detain the kid who was NOT committing a crime, Zimmerman committed assault, possibly battery if he touched the kid, maybe even kidnapping and false imprisonment. Zimmerman was the aggressor. As far as we know so far, kid did not commit any crimes.

Naturally, we don't know all the facts yet, but what we do know makes Zimmerman look guilty to me and most people except you, apparently.

It's obvious to anyone with any intelligence that you are RACIST. If it were possible that anyone who had opinions like yours would automatically have the same fate that this lovely young man suffered, happened to your child born now or in the future, would you be of the same opinion.

But you're probably thinking that it won't ever happen to you but what if something worse did and the person who perpetrated it would try to hide wrongly behind this ridiculous "law". But you know what as I write this I'm wondering if you are intelligent enough to even ask yourself that question. I somehow doubt it.

During the time to blog this reply, at least 10 white people have been killed by other WHITES. ( contrary to your racist notions, whiltes kill at a rate 4 times more than blacks. They just dont get put in jail as often. Fact, not fiction).

HoustonSteve, you said both of the individuals involved were of limited intellect. What in this fact pattern indicates to you that the kid was of limited intellect? Clearly, a grown man, overzealous self-appointed "captain" of the neighborhood watch who calls the police on a daily basis to complain of open garage doors is of limited intellect. But what did the kid do? If I, a grown 31-year old man, were visiting a neighborhood (kid wasn't from around there) and was being followed by a heavy set man WITHOUT A UNIFORM who got off his car and confronted me, I probably wouldn't be as easy-going as you say the kid should be. Politely answer his questions? You think Zimmerman was polite after telling cops that these "mother^&@^*" get away all the time?" You think Zimmerman was polite after telling cops the kid was probably "on drugs." My man, I've read some of your comments, and you've made some decent points, but you reek of the same racism Zimmerman felt compelled to act upon.

I think George Zimmerman had been playing this little "I'll save the home-owners-association and be a hero by using my gun to stop an intruder" fantasy out in his head for quite some time.

He was simply waiting for the opportunity. If it had not been Trayvon, it would have been someone else soon enough.

I hope he realizes now that we do not view him as a hero, but as a coward.

A man who killed someone half his size and half his age. A man who killed someone that posed no threat to the community from whom he desperately sought acceptance and adulation.

He needs to be deprived of his liberty, and sent to jail. But at the very least, he has been deprived of the laural wreath he fantasized about, and instead will be forever remembered for the dunce-cap he dons today.

GOD- I beg to differ. There are a lot of facts that matter. I agree zimmerman was an i-diot to bring a gun along and chase him. But if he thought he was legitimately a criminal, then this is not smart, but not illegal. I think the FL laws with respect to concealed carry are ridiculous, but it sounds like Zimmerman obeyed the law there too. The fact the kid was unarmed was something Zimmerman couldn't have known (yet another reason he shouldn't have chased, but still not reason he is guilty of second degree murder). The fact that the kid was face down doesn't mean anything. He could have been on top of Zimmerman and flown off backwards when he was shot. If he was face down and ballistic analysis shows that he was shot IN THE BACK, then that's another matter. But we don't know the ballistic data yet, do we? That's the trouble with judging the guy without all the facts.

HoustonSteve, YES, even if Zimmerman genuinely thought the kid was a criminal, when Zimmerman attempted in any way, shape, or form to detain the kid who was NOT committing a crime, Zimmerman committed assault, possibly battery if he touched the kid, maybe even kidnapping and false imprisonment. Zimmerman was the aggressor. As far as we know so far, kid did not commit any crimes.

Naturally, we don't know all the facts yet, but what we do know makes Zimmerman look guilty to me and most people except you, apparently.

Oh, and if it is found that Zimmerman did, indeed, commit a felony (felony battery, false imprisonment, kidnapping), he is also guilty of capital murder and subject to the death penalty because he used a gun during the commission of a felony.

No doubt this is a travesty and Zimmermann going into hiding would at the very least be an admission of guilt – in addition to 'fearing for his very life'; as a weapon owner and a disabled veteran, it is obvious Zimmermann has/had some ulterior motive(s) but none will come to fruition; his life as he knows it is over; finito forever. His life sentence has begun. Fools with guns.

EzErik- as I said in an early post, right now, knowing limited facts, Zimmerman looks guilty to me too. I am just suggesting that an investigation be conducted and collect such things as forensic evidence, ballistic evidence, and eyewitness testimony and THEN judge. We lack MANY of the facts.

People are letting their emotions cloud their judgement. I am just proposing two different scenarios where we would probably all agree on the OPPOSITE outcome. As I said, suppose that it turns out zimmerman was the one on his back and was screaming for help and THEN shot. Now suppose that his claim that the kid acted guilty turned out to be verified by the fact that the cops find stolen items from recent burglaries in the area in the kid's car. Now contast THAT situation to one where an eyewitness saw zimmerman over the kid firing down on him and the ballistics verify this, and it turns out the kid had NO stolen items and was totally INNOCENT. Two totally different, yet still possible scenarios. We must have all the facts.
